The usage of a robust beamforming and scanning algorithm needs a significant research before use it properly in 6G. In addition, other parameters need to be investigated, which include low-complexity, low-power hardware circuits, channel and noise modeling, energy efficient modulation schemes, low density channel coding, ultra massive multiple-input and multiple-output (MIMO) systems, and powerful synchronization schemes [1]}. The visible light communication using optical wireless communication is one of the most preferable technologies in the 6G architecture [2]}. In 6G, the use of light-emitting diodes (LEDs) can help us in the high-speed data communication. Fig. REF  illustrates the technological enhancements of cellular networks, that lead to the era of 6G.
